Math Problem Statement

Solve the system of equations: y = x + 5 and y = 10x - 6. Round to the nearest hundredth.

Solution

The system of equations provided in the image is:

  1. y=x+5y = x + 5
  2. y=10x6y = 10x - 6

To solve this system, let's set the two expressions for yy equal to each other since both equal yy:

x+5=10x6x + 5 = 10x - 6

Now, let's solve for xx:

x+5=10x6x + 5 = 10x - 6

Subtract xx from both sides:

5=9x65 = 9x - 6

Next, add 6 to both sides:

11=9x11 = 9x

Finally, divide both sides by 9:

x=1191.22x = \frac{11}{9} \approx 1.22

Now, substitute x=1.22x = 1.22 into either of the original equations to find yy. Let's use y=x+5y = x + 5:

y=1.22+5=6.22y = 1.22 + 5 = 6.22

So, the solution to the system of equations is:

(x,y)(1.22,6.22)(x, y) \approx (1.22, 6.22)
